Used by the pros.

Look in any pro mechanic’s tool box, and you’ll find a bottle of Dumonde Tech Original Chain Lube. It’s a bit more viscous than the commonly-used Dumonde Tech Light, but we’ve found it holds up a bit better to bad weather and gritty conditions.

Lube of choice

Familiarity: I've used it several times

Like most bike parts you try out different products until you find something you really like. Well this is the chain lube for me. This stuff is nice and light on your chain and holds for a really long time. I usually apply every week or two depending on how often i am riding. This stuff isn't gloppy like other brands, and gets it super clean. Do yourself a favor and pick some up! If you are new to biking and need some helping getting going feel free to reach out anytime!

Cant beat it

Familiarity: I've put it through the wringer

I was using some other chain lube with a weird applicator until my friend let me use his which happened to be this brand of lube. I immediately went home and ordered some, and couldn't be happier. Great product!

best chain lube there is

Familiarity: I've put it through the wringer

I've used this lube for years after trying many different kinds, a little goes a long way, its nice and viscous and makes the chain roll really well!...if you ride MTB a small dab of this is also good for your fork seals

The best for a range of conditions

Familiarity: I've put it through the wringer

I have used extensively, and tested just about every chain lube out there; I rather enjoy seeing what is going to provide the best friction reduction, shifting, and lasts longest; while obviously running reasonably clean. My obsession with chain lubricant came with advent of 11-speed drive trains, as a few of us were seeing at most 800 miles out of chains with out typical go-to lube.

While we can't ask any lube to run completely clean, Dumond Tech has the perfect viscosity to only leave a thin film on your drivetrain, rather than the piles of goop you can get with wax-based lubricants.

This lube is light enough to run fairly clean, but thick enough that it doesn't make a mess during application. It also has a great lifespan per application; I have been getting around 120 miles per application before noticing that my chain is sounding rather dry. I have yet to shed all of the lube and have my ride sounding like something headed for the junk yard.

This works equally well on the road and mountain; I highly recommend it if you have diverse conditions, and especially in harsh conditions.

Rides so smooth

Familiarity: I've used it several times

Just got this in the mail a few days ago. I've used it a couple of times. Easy application, bike rides smooth after. I only use a tiny amount, I'm sure the 4 oz bottle will last me a month or two, and I wash my bike pretty much every day.

Better than sliced bread

Familiarity: I've put it through the wringer

I can log 60-100 miles in so cal dry dusty trails before having to reapply. Most of the people here using other lubes make it 20 miles and have to relube. This stuff is awesome and my chain stays much cleaner!

One lube to rule them all

Familiarity: I've put it through the wringer

This stuff is great for just about any condition. It holds up in wet conditions and also when it's really dusty. I'll use the Lite (yellow) version on my road bike when conditions are dry, but the Original (blue) is my standard choice for mtb riding.

High Quality

I ride my mountain bike 2-4 times/week here in Park City. I try to clean it every week or so and reapply Dumonde to my chain afterwards to help keep everything in good shape. It works great and is reasonably priced.

Simply The Best

Familiarity: I've put it through the wringer

This lube is truly the best I've ever used. I never liked the wax type. Typical oil type lubes wash off too easy and create major build up. This is not too oily after wiped off and only needs to be re-lubed every 4 or 5 rides with a simple brush off in between. truly amazing. BTW, I ride mostly dry and dusty trails here in Southern California so I cannot speak to real wet weather climates.

Lasts long on long rides

Familiarity: I've put it through the wringer

This is a great lubricant and keeps a quiet running drive train. I use this on my mountain bike. It's hold up through long rides and in dry or wet weather. Just simply follow the directions on the bottle and you won't be disappointed.

Good Stuff

Comment on WONKA's review:

my Mtb loves it.

And I put my bikes through hell. Come next winter, I'm going to be very happy I picked up the heavier lube. Most lubes out there are too thin for a proper winter commute or trail, but this one looks like it will hold up.
